Made for Hampstead Homes
Aluminium glazing is the ideal choice for Hampstead properties. Whether you’re upgrading a period conversion, fitting out a modern new build, or opening up a rear extension, DuraJoin’s slimline, energy-efficient frames bring clean lines and lasting results.
We work directly with homeowners, architects, and contractors across Hampstead, including South Hill Park, Fitzjohn’s Avenue, Frognal, and the Vale of Health. Every order is made to measure and installed by our in-house team, with no subcontracting or shortcuts.

Slim Sightlines, Strong Results
Aluminium frames are slimmer and stronger than uPVC or timber, making them ideal for contemporary designs or clean retrofits. Every window and door comes with high-security locks, long-life coatings, and thermal break technology.
DuraJoin units offer:
- Multi-point locking
- Secured by Design options
- Low U-values and warm-edge spacers
- Powder-coated finishes to any RAL colour
- Double or triple glazing available
- Acoustic, solar control, and laminated glass upgrades
We also supply trickle vents, integrated blinds, and threshold options where needed.
Why Aluminium?
Aluminium frames are increasingly chosen for performance and durability. Unlike timber, they do not warp or swell. Unlike uPVC, they retain their finish and rigidity long term. Our clients in Hampstead choose aluminium for the following reasons:
- Modern look with uninterrupted glass spans
- Long-term value and minimal maintenance
- Suitable for conservation and heritage properties when designed correctly
- Can be thermally and acoustically upgraded
All DuraJoin products meet or exceed Part L requirements for energy performance.
Installation Process
Every project begins with a free site survey. We assess access, dimensions, ventilation needs, and compliance. We also flag any details that may require Building Control or Conservation Officer input. After approval:
- CAD drawings are produced if required
- Old units are removed and responsibly disposed
- Frames and glazing are fitted by our in-house team
- Internal trims and external sealing are completed on-site
- Final sign-off is completed only after checks and cleanup
Most installations take 1–2 days, depending on scope. We coordinate with builders where needed.
Finishes and Frame Options
DuraJoin offers a wide selection of frame colours and configurations. Whether you need dark, modern sightlines or traditional finishes for a Victorian home, we can match the design language of your property.
Options include:
- Over 200 RAL colours available
- Dual-colour frames for interior/exterior contrast
- Anodised or textured coatings for durability
- Heritage-style bars and glazing layouts
- Low thresholds for accessibility
You’ll also be able to select from various handle styles, locks, and hardware brands.
Planning Permission in Hampstead
Most window and door replacements fall under Permitted Development. However, if your property is:
- In a conservation area
- A listed building
- Part of a flat or maisonette
- Within a building with shared ownership or leasehold restrictions
Then planning permission or Listed Building Consent may be required. DuraJoin works with local planning consultants and can provide drawings, specifications, and documentation for approval if needed.
We recommend always checking before placing an order. We’re happy to help.
Thermal and Acoustic Performance
All aluminium products from DuraJoin are engineered for energy efficiency. Our systems include:
- Polyamide thermal breaks to reduce heat loss
- Warm edge spacer bars for better glazing insulation
- Low-E or triple glazing to meet performance goals
Where street noise or aircraft traffic is an issue, we offer acoustic glazing units tailored to reduce sound intrusion.
Our installations help improve energy ratings and comfort in both older and newer homes.
Aftercare and Guarantees
Every installation is covered by product and workmanship guarantees. We also provide full documentation, including energy ratings, safety markings, and maintenance instructions.
Aluminium frames require little maintenance:
- No repainting
- Just occasional cleaning with mild detergent
- Hardware and seals rated for long-term use
If you ever need support after the job is done, we’re easy to reach and quick to respond.
